Net 30 Payment Terms (2026): What Net 30 Means, the Real Cost of 2/10 Net 30, and When to Offer It

What does net 30 mean?

As of 2026, net 30 means the full invoice amount is due 30 days after the invoice date. "Net" is the total after any discounts or credits you agreed to, and in common use the 30 days are calendar days counted from the date on the invoice. An invoice dated September 14 is due October 14. The term is simple. What it does to your cash, and what a "2/10" in front of it really costs, is the part most businesses never work out.

Sourcing note: the discount rates, due dates, and cash figures on this page are arithmetic on the terms themselves. Payment fees are from stripe.com/pricing, and the federal late-payment interest rate is from the Treasury's Prompt Payment page, read September 14, 2026.

Net 30 payment terms, with real due dates

The common terms, all counted from an invoice dated September 14, 2026:

Two things follow from the table. First, the clock starts on the invoice date, not the day you finished the work, so every day an invoice sits unsent adds a day to how long you wait. Second, "net 30" alone leaves room to argue about business days or days from delivery. Print the actual date ("Due October 14, 2026") next to the term and there is nothing left to interpret.

What does 2/10 net 30 mean?

2/10 net 30 means the customer takes 2% off if they pay within 10 days; otherwise the full amount is due in 30. On a $10,000 invoice, that is $9,800 by day 10 or $10,000 by day 30. It sounds like a small courtesy. It is not: a customer who skips the discount is paying $200 to keep $9,800 for 20 more days, and annualized that is about 37% ((2 / 98) x (365 / 20)). No invoicing tool prints that number, so here it is for the common early-payment terms:

If you are the buyer and your cash or credit line costs less than those rates, take the discount every time. If you are the seller, read the same table from the other side: offering 2/10 net 30 is paying 37% a year to get your money 20 days sooner.

What 2/10 net 30 costs the business that offers it

More than it looks. Say you bill $40,000 a month and half your customers take a 2/10 discount. That is $20,000 a month collected 20 days early, for $400 a month, or $4,800 a year. Most businesses can find cheaper ways to fund 20 days of cash. Offer the discount when getting paid sooner is worth more to you than the 2%: a tight month, a big supplier bill, or a customer who otherwise pays late. Otherwise, fix how fast you invoice and follow up before you discount the price.

Net 15 vs net 30 vs net 60: the cash each one ties up

The longer the term, the more of your own money sits in your customers' bank accounts. If every customer paid exactly on the due date, a business billing $40,000 a month would always be owed roughly this much:

That is the best case, because customers who pay late push every number up. Moving from net 30 to net 60 does not cost you a fee; it costs you a full month of revenue that you now have to fund from somewhere else. A sensible default for a small service business: due on receipt or net 15 for new customers and small jobs, net 30 when a customer's accounts payable team requires it, and net 60 only when the contract is worth the cash it ties up.

Should a small business offer net 30?

Offer it when the customer expects it, and protect yourself when you do. Many larger companies pay vendors only on terms, so refusing net 30 can cost you the account. What net 30 should never be is the default for a first job with a customer you do not know yet. Three rules keep it safe:

• Take a deposit on new work. Terms apply to the balance, not the whole project.
• Agree the terms before the work. Put the term, the due date rule, and any late fee in the quote or contract the customer accepts.
• Invoice the day the work is done. On net 30, a week of invoicing delay is a week of waiting added to every job.

How do you get paid on time on net 30 terms?

Most late payments are not refusals; they are invoices that nobody on the customer's side looked at until someone asked. Make it easy to pay and hard to forget:

• Put the due date, not only the term, on the invoice.
• Send reminders on a schedule: a few days before the due date, on the due date, and a week after. The first reminder after the due date is the one that usually gets the invoice paid.
• Offer bank payment on large invoices. At Stripe's published rates, a $5,000 invoice paid by card costs you $145.30 (2.9% + 30¢), and the same invoice by ACH Direct Debit costs $5, because ACH is 0.8% capped at $5. Our Stripe fees breakdown has the full table, and ACH vs wire transfer covers how long each takes to land.
• Let the customer pay from the invoice itself, with a payment link, instead of asking them to mail a check or set up a vendor record first.

If reminders are still being written by hand, invoice automation software handles the schedule, and accounts receivable automation covers the rest of the path from invoice to cash.

What is a net 30 account?

A net 30 account is the buyer's side of the same terms: a vendor account that lets your business buy now and pay 30 days later. Business owners often open them to build business credit, because some vendors report on-time payments to business credit bureaus. Not every vendor does. Before you open one for that reason, check the vendor's own page for whether it reports and to which bureau, and pay early enough that a slow bank transfer never makes you late.

Is net 30 business days or calendar days?

In common use, calendar days from the invoice date. Nothing makes that automatic, though, and a customer's accounts payable team may count from the day they received the invoice or approved it. The fix costs nothing: print the due date on the invoice, and if your contract counts from delivery or uses business days, say so in the contract.

Can you charge a late fee on a net 30 invoice?

Usually, if the customer agreed to it before the work. A late fee that appears for the first time on an overdue invoice is hard to collect and easy to dispute. States limit late fees and interest differently, so check your state's rule before you pick a rate. For comparison, the federal government holds itself to the same idea: under the Prompt Payment Act of 1982, federal agencies owe interest when they pay a vendor's proper invoice late, at a rate the Treasury sets, which is 4.75% for July 1 to December 31, 2026. The Treasury also tells agencies to pay small businesses early when it is in the government's interest.

The bottom line

Net 30 means paid in 30 days from the invoice date, and on its own it is a fair, normal term. The costs hide around it: 2/10 net 30 is a 37% annual rate for whoever is on the wrong side of it, net 60 doubles the cash you are owed at any moment, and every day between finishing a job and sending the invoice is a day added to the wait. Set terms before the work, print the due date, take a deposit from new customers, and automate the reminders.
